Cave3D

Cave3D is a 3D viewer that lets you see your cave survey while you are taking it, inside the cave, and analyze it in relation to a digital terrain model and other caves, on the spot. You can move, zoom, rotate the 3D view of the cave. 3d wall can be reconstructed from the splays. Surface DEM can be loaded from a ascii grid file, and surface textures from a geoTiff or OSM map.
